Professional Applications & Engineering Value

These M1.6 TRS thread forming screws are specifically engineered to solve common fastening challenges in plastic assembly applications. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength required for durable connections. The thread forming design eliminates the need for separate tapping operations, creating strong mating threads that resist loosening from vibration and thermal cycling. With a blunt tip that prevents plastic material splitting and a fully threaded shank that maximizes grip length, these metric tapping screws deliver reliable performance in electronic enclosures, automotive trim, consumer products, and other precision plastic assemblies where space constraints demand compact M1.6 fastening solutions.
